Fun fact: The poem refers to Cape Clear Island off the coast of Ireland. Clear Island or Cape Clear Island (officially known by its Irish name: Cléire, and sometimes also called Oileán Chléire) lies south-west of County Cork in Ireland. It is the southernmost inhabited part of the island of Ireland and has a population of over 100 people. Officially it is a Gaeltacht (Irish-speaking area), and most inhabitants speak Irish and English. Archaeological sites on the island include a prehistoric cup-marked stone (moved to the island’s museum), a fulacht fiadh at Gort na Lobhar, a neolithic passage tomb at Cill Leire Forabhain, several standing stones around the island, a promontory fort at Dún an Óir, and a signal tower dating from the Napoleonic Wars. The island also has a number of early Christian sites, and is reputed to be the birthplace of Saint Ciarán of Saigir. The ruins of 12th century church are close to the main pier.
